RUN Mode
Normal operation of the D11 Expert is called the "RUN mode". The LED indicators
operate in the RUN mode, as follows:
The Signal Strength indicator is Banner's exclusive AID™ (Alignment Indicating Device, U.S. Patent #4356393). This feature
makes alignment during the TEACH mode easy and accurate and provides a means of signaling when maintenance is needed
whenever in the RUN mode. Whenever the pulse rate is slow, the fiber sensing ends should be cleaned and/or the alignment
checked.
TEACH Mode
Sensitivity is automatically set (and optimized) by "teaching" the sensor the light and dark conditions. This is accomplished in the
TEACH mode. The TEACH mode simply requires that each of the two sensing conditions be presented to the fiber optics. When
the push button is clicked, the sensor samples the sensing condition and registers it into memory. After the second sensing
condition is registered, the D11E automatically sets the sensitivity to the optimum value for the application, and then returns to the
RUN mode.
Note: There is a period of a few seconds at the end of the TEACH mode before the RUN mode begins.
Light or Dark Operate Selection
The two sensing conditions may be presented in either order: the light condition, first, and then the dark condition, or vice versa.
The condition which is presented first sets the condition for which the output will energize. In other words, the output will be light
operated if the light condition is TEACH condition #1, or the output will be dark operated if the dark condition is TEACH condition #1.
Indicator LED Color Function
Power
"ON"
Green 1) On steadily whenever power is applied
2) Flashes at approximately 4Hz to indicate that the
output is overloaded
Output
Indicator
Yellow Follows the action of the output:
On when the output is energized
Off when the output is de-energized
Signal
Strength
Red Lights whenever the sensor "sees" its modulated
light source and pulses at a rate which is
proportional to the received light signal strength
